Thanks, I found that list on Wikipedia too, but there's very little meat
there. They mostly seem to involve bad sectors to prevent people
ripping them. If we're hitting bad sectors on the original disc, it
reconfirms my feeling that if we follow the all navigational jumps in
the DVD VM, we shouldn't have (as many) problems.
